Abstract: 203,637. Haddan, A. J. H., (National Cash Register Co.). June 9, 1922. Cash registers; with item-printing mechanism. -Relates to cash registers of the type in which the autographic record strip receives impressions by means of a stationary platen from movable type carriers and comprises feed mechanism adjustable for variable feed for the autographic record strip. The record strip passes from a supply roll 642, Fig. 1, round guide rolls 643, 644, 645, 647 and 648 to the receiving roll 649, the guide rolls 644 and 648 being carried on a lever 654, Fig. 7, fast on a shaft 655 having a forked arm 664 engaging a pin on a threearmed lever 667 rocked by cams on a shaft 515. The guide rolls 644, 648 are thus moved sufficiently to bring the printed item from the impression point to the writing aperture. To give a feed movement for spacing the items, the lever 654 is pin-and-slot geared to a lever 673, pivoted at 651 and having a hook 674 to engage a pin 675 on a lever 676 loosely pivoted on the spindle of the receiving roll. The lever 676 carries a clutch roll 68, adapted to bear between the internal surface of a drum 683 attached to the receiving roll 649 and a surface 684 on the lever 686. The lever 676 is urged by a tension spring so as to follow the lever 673 until the former lever meets a stop arm 1679, during which movement the clutch roll 681 is inactive; back drag of the receiving roll being prevented by a similar spring- urged roll 686. On the return movement, the lever 673 picks up the lever 676 which rotates the drum 683 and the receiving roll. To vary the spacing of the printed items, the position of the stop 1679 is altered by means of a lever 690 pivoted at 655 and fast with an arm 691 connected to the bent lever 680 to which the stop 1679 is pivoted. To compensate for the increasing thickness of paper on the receiving roll, an arm 679 is provided, rigid with the stop 1679 and having a roller bearing against the wound-up strip. The means for effecting the impression of the typewheels is described in Specification 203,639.

Patent GB-972580-A (GB)
Title: A typewriting machine with two ribbon guides
IPC: B41J35/23
Filed: 1961-06-07
Abstract: 972,580. Ink-ribbon mechanisms. OLYMPIA WERKE A.G. June 7, 1961 [June 18, 1960], No. 20538/61. Heading B6F. A typewriter (manual or electric) has selectively operable guides 1, 3 respectively for the normal two-colour ribbon 2 and a once-through carbon paper ribbon 4, the latter being fed, only when being used, by a friction drive acting on the ribbon itself. Each time a typing action occurs a rod 25 is pulled forwards to swing a bell-crank 24 anticlockwise about shaft 23 against spring 27 and this depresses a pull lever 29 the upper end of which is pivoted in a slot of shift guide 28b formed integrally with lifting lever 28 for ribbon guide 1. Thus guide 28b and lever 28 are swung anticlockwise about their pivot to raise guide 1 at each typing action. Depending on whether lever 29 acts on the near end of the slot, further along the slot, or in the first enlargement of the slot the ribbon will be raised to type blue, raised more to type red, or not raised for stencilling. The slot has a further enlargement 28c and when lever 29 acts in this, lever 28 is not moved but a dog 29a on lever 29 engages a bent end 30a of lever 30 to raise guide 3 for the carbon paper ribbon. The position of lever 29 in the slot is set by rotating a cam 19 which, through push rod 20, rotates shaft 23 and lever arm 23a which swings lever 29 by connecting rod 23b. Ribbon feed.-Carbon paper ribbon 4 is fed from a braked supply spool 5 through guides 3 and 7 to waste spool 6 by intermittently-driven friction rolls 8, 9 driven through shaft 12 by a pawl and ratchet 11, 10 operated at each typing action by oscillating lever 17 carrying the pawl. When the normal ribbon is being used, push rod 20 is retracted and tensions a spring 20d between the pawl and an extension of rod 20 so that the pawl is out of engagement with the ratchet. When the carbon paper ribbon is in use, rod 20 is pushed back and the spring is relaxed to allow engagement of the pawl with its ratchet and, hence feed of the carbon-paper ribbon. Waste spool 6 is driven through a resilient slipping pulley 14 by the ratchet mechanism, the drive ratio being such that the feed is satisfactory whatever the effective diameter of the waste spool.

Title: Separating and testing plug contact, particularly for use with soldering tag strips in telecommunication technique
IPC: H01R12/50
Filed: 1962-05-29
Abstract: 960,775. Plugs and jacks. KRONE G.m.b.H. May 29, 1962 [June 7, 1961], No. 20574/62. Heading H4K. In a jack having two contact strips which lie resiliently against each other, the strips are arranged so that the initial insertion of a plug causes one at least of the strips to be moved in a first direction without breaking the contact between the strips and further insertion of the plug causes said one strip to move in a direction perpendicular to said first direction, thereby breaking the contact. As shown, insertion of a plug 16 between the ends 11, 12 of contact springs 2, 3 causes them to move in a first direction, i.e. end 12 in the direction of arrow V, without breaking the contact at the crosspoint of the springs. On further insertion of the plug, ends 11, 12 ride-up suitably shaped portions 19 on the plug, whereby these ends are moved in a direction perpendicular to the plane of the paper, thereby breaking the contact. One of the contact springs may be a rigid plate (Figs. 6-9, not shown) or flat springs having protruding contact members (Figs. 13-16, not shown) may be used.

Title: Operation of change-speed gearing
Inventor: WATTS LAURENCE DEREK
IPC: F16H59/04
Filed: 1957-01-04
Abstract: 831,486. Change-speed control; ratchet gearing. SCAMMELL LORRIES Ltd. April 2, 1958 [Jan. 4, 1957], No. 20709/56. Classes 80 (2) and 80 (3). [Also in Group XXIX] A ratio shift lever 4 controlling planetary gearing in a motor vehicle is oscillated back-andforth about a journal 7 so that one or other of two pawls 16, 17 rotates a drum 5 step-by-step, compressed air fed in through a pipe 33 to a space 34 in the drum then being fed through spring-biased piston-like ports 42 to ports 39 in the housing 1 surrounding the drum and leading through pipes to ratio-establishing brakes in the gearing. The gearing may be a four-speed and reverse planetary gear in series with a twospeed planetary gear. The pawls 16, 17 are pivoted by bolts 22 upon the ratio shift lever 4, and are biased by an inverted U-spring 19 to engage teeth 18 on the drum. A cam 25 on the control housing 1 is so positioned as to disengage the inoperative pawl, e.g. 17, when the other pawl (16) is operative to turn the drum. Detent rollers 26 on levers 27 pivoted upon the casing 1 are biased towards each other by a spring 29 and engage the teeth 18 to hold the drum in a selected position. The piston-like ports 42 in the drum may be made from nylon or carbon. The shift lever 4 is restored to its central position by spring-biased plungers 9 in the housing 1. A catch 45 on the casing normally lies in the path of a lug 46 carried by the drum 5 and limits rotation of the drum 5 to prevent a down-shift into neutral. To engage neutral, a knob 51 on the ratio shift lever 4 is depressed against spring bias so that a plunger 50 engages a lever 47 to withdraw the catch 45 from the path of the drum lug 46. Alternatively, the catch 45 may be modified to prevent the ratio shift lever 4 being moved from the neutral to the reverse position. A governor responsive to engine speed supplies hydraulic or pneumatic pressure to a plunger 58 which, while a predetermined engine speed is exceeded, is projected into the path of the ratio shift lever on its down-shift side to prohibit a down-shift. A switch 57 in the vehicle engine starter circuit is closed only by a cam 56 carried by the drum 5 when neutral has been established in the gearing. A pointer 53 moving over a dial 54 indicating the ratio established in the gearing, Fig. 4 (not shown), is located exteriorly of the control housing.

Title: Improvements in electric transformer
IPC: H01F27/20
Filed: 1925-08-19
Abstract: 254,133. Dehn, F. B., (Products Protection Corporation). Aug. 19, 1925. Transformers in which a gas is used as the insulating and cooling medium have bare, spaced conductors for the primary and secondary windings and a funnel for causing the flow of the gas up through the windings and down on the outside near the casing. The casing is formed in two parts 1, 2 welded together, the upper part 2 being domed and of smaller diameter than the main part. Holes 6 are made in the top of the domed part and are connected to similar holes in the curved top of the main case 1 by outside channels 8. The funnel is formed of four plates 80, Figs. 5 and 8, placed inside the main case, a tapered part 81 and a tube 82 all made of dielectric material; the tube 82 is centred by ribs 14 on the upper case part. The plates 80 do not reach to the bottom of the main case, the cooling gas, which may be nitrogen or nitrogen helium, passing up inside the funnel and down between the plates 80 and case 1 and then under the plates 80. The core 15 is built up of L- shaped laminated plates, clamped between angle irons 16. Top and bottom rings 21 are carried by brackets 20 bolted to the angle irons. The groups of laminae are tightened by bolts 22 in the brackets 20 bearing the plates 23. The rings 21 support inner rings 25 to which are attached Y-shaped parts 27 carrying vertical bars 35 of dielectric on which the high tension winding 32 is placed. The bars taper from the centre to their ends. The coils may be placed in slots cut in the bars as shown in Fig. 8 or they may be carried by slotted spacers 37, Fig. 13, formed with integral vertical ribs 36. In a modification, plain plates 45, Fig. 17, are used with vertical spacing strips 46. Where thin wires are used for this winding vertical insulating sheets of thin dielectric material are placed between adjacent parts of the coils; these sheets are perforated and supported by pegs resting on the wires. All the coils are of bare wire, each coil spaced from the next so that the gas may circulate over all the coils. The end of one coil is carried suitably across the coil to the inside of the next coil. The low tension winding 65 is inside the high tension winding and consists of two bare wires of large cross-section; the adjacent turns are separated by spacing strips 66 on insulating bars 70 which are placed between the rings 25 and against the parts of the core. The outer edges of the spacing strips 66 terminate inside the edge of the wires so that the cooling gases have direct access to the wire. The core parts are insulated from the brackets, angle irons &c. by sheets of dielectron; molten lead is run between the outer edge of the core parts and the casing, and the domed bottom 3 is welded to the main case 1 after the transformer parts have been put into place. The high tension winding leads are taken to terminals 61 at the top of the transformer and the low tension terminals are at the side of the case 1.
